2000 Xterra 3.3 w/ 172k miles, timing belt changed at 124k (when I bought it). Wife calls and said truck died going down the road. Get there, cranks but will not start. Tow it to the house, pop the hood and start having a look. Put my hand on the dist cap and the whole distributor moves. I look down and see the hold down bolt is gone and part of the plate it screws in to is missing. Remove the cap, pull the connectors and pull the distributor, shaft is seized solid. Notice some bits of metal of the hole, but the gear on the dist looks ok. Hard to believe it ate the gear on the cam instead of the distributor or shearing the roll pin that holds the gear but that appears to be what happened when it seized.
Couple questions. First obviously, has anyone ever had this happen before? Is the distributor drive gear replaceable without replacing the whole cam (which will be a major pita). Is there enough room to slide the cam out without pulling the head. Is it likely that the motor jumped the timing belt and bent some valves when the distributor stopped the cam?
Thanks in advance.
